The rear-panel EIA-232 serial port is available when you disable Modbus®
protocol support by monitor settings. You can connect the monitor rear-panel port to a
local PC, modem, or SEL-2020/2030 Communications Processor. Fiber-optic cable
modems are also available for communication at distances greater than 50 feet (15.2
meters). Use the SEL-5801 Cable SEL
ECTOR
software (available for free download at
the SEL web site, www.selinc.com) to determine the correct metallic or fiber-optic
cable for your particular application. If you prefer to build your own, this software also
shows the cable pinout for metallic cables.
EIA-485 Communication Cables
The SEL-701-1 Monitor is equipped with a rear-panel EIA-485 serial port
connector which operates using Modbus protocol when you enable that feature by
monitor settings. Connect the SEL-701-1 Monitor EIA-485 port to a Modbus Master
device as shown in
.
NOTE:
When you enable Modbus protocol for the rear-panel
serial port, the monitor disables the EIA-232 serial port and
enables the EIA-485 serial port.
